How should extra cable length on GPS or satellite radio antennas be managed?

Managing extra cable length for GPS or satellite radio antennas is critical to maintaining optimal performance and avoiding signal interference. Coiling the excess cable in a loop near the unit is a preferred method because it helps prevent the cable from being pinched or damaged while also maintaining the integrity of the signal. This approach minimizes the risk of interference that can arise if the cable is too tightly wound or improperly managed.

Leaving the cable slack can lead to unintended movement or vibration, which may negatively impact the antenna's performance over time. Additionally, cutting the cable to size can be impractical; once cut, the cable cannot be reused, limiting future adjustments or installations. Taping the cable flat against the unit could create pressure points or stress on the cable, potentially leading to wear and tear or signal degradation.

By coiling the excess length, the integrity and functionality of the antenna system is preserved, providing a balance between functionality and practicality in cable management.
